摘要：美国审计总署(GAO)每年都会对美军的国防采办项目进行评估,以防控在国防采办中出现的风险。GAO在获得项目的关键技术、成本、进度等信息,以及在研发、生产过程中产生的统计数据后,采用基于知识的国防采办风险评估方法,对国防采办项目进行评估,提示项目全寿命周期中存在的风险。该方法在国防采办过程中设置三个关键知识点,分别对资源与需求匹配性、产品设计稳定性、生产过程成熟度进行分析。本文详细介绍了美军基于知识的国防采办风险评估方法,并以美军先进反辐射导弹AGM-88E项目为例进行介绍,最后提出了对我军国防采办启示。

摘要：Auxin/indole-3-acetic acid(Aux/IAA)是植物中一个重要的基因家族,在生长素信号传导中扮演着关键的角色,参与了植物的生长、发育以及对逆境胁迫的响应和调节过程。本研究通过分析丹参(Salvia miltiorrhiza)不同羽状复叶的转录组数据筛选了潜在的与叶片发育相关的基因SmIAA7,设计特异引物成功从丹参中克隆了SmIAA7,并进行生物信息学分析、原核表达和纯化、亚细胞定位、生长素及非生物胁迫下的诱导表达分析。SmIAA7基因全长684 bp,编码227个氨基酸,蛋白分子质量25.3 kD。保守结构域分析表明SmIAA7含有超家族保守结构域Aux_IAA(pfam02309),序列分析及系统进化树结果表明SmIAA7和其他植物中的IAA7以及IAA14同源性较高,可能参与植物的生长发育并响应逆境胁迫。构建原核表达载体pET28a-SmIAA7并在大肠杆菌Rosetta(DE3)菌株中成功表达SmIAA7重组蛋白,纯化得到可溶性重组蛋白。亚细胞定位实验结果表明SmIAA7定位于植物细胞的细胞核中。实时荧光定量PCR结果表明,SmIAA7基因能够响应生长素的诱导导致表达水平升高。干旱、低温以及盐胁迫均能够显著提高SmIAA7基因的表达水平。本研究为进一步揭示SmIAA7在丹参叶片发育、信号传递及逆境防御中的作用奠定基础。
